Paul Ogorzow (German link) plied his trade in a city blacked-out against British bombing, but he provides an illuminating glimpse at criminal investigation.

While Ogorzow benefited from Berlin’s preternatural darkness, he didn’t go greatly out of his way to cover his tracks otherwise. At least four of his eight murders were within a mile of his house; one woman who survived his attack reported the assailant was wearing German Railways kit.

The police, prone then as now to (sometimes hastily) settle on a theory and seek evidence to confirm it, remained blind to the seemingly obvious possibility that a railway worker was the culprit … even if he also happened to be a Nazi party member in good standing.

The official fixation on Untermenschen may not be surprising given the ideological climate, but Germany had had its share of noteworthy murderers in the interwar years who were neither Jews nor foreign laborers nor British agents — the suspect profiles favored by German investigators while Ogorzow continued his killing spree.

With the slightest measure of care, the S-Bahn Murderer might have plied his hobby unmolested until the wartime manpower shortages started making him look like an attractive bit of cannon-fodder for the eastern front. Alas for him, his voracious appetite for murder — eight victims with similar m.o. in just a few months — eventually made him so obvious that even the police could no longer overlook him.

Although the government kept the crime and its unedifying investigation fairly quiet, it was known. There was even a 1944 true crime potboiler by Wilhelm Ihde (pseudonymously writing as “Axel Alt”), Der Tod fuhr im Zug (Death Rode the Train). According to Todd Herzog,

Alt’s novel is representative of the dominant tendency of the period to celebrate the work of the criminal police while avoiding any portrayal of the totalitarian apparatus that surrounded criminal politics in the Third Reich.

Little surprise there.

Alt’s novel ultimately aligns itself with [Fritz] Lang’s film [M] in showing the methodical work of professional detectives to be ineffective in capturing the modern killer and explicitly calling for … recruitment of the public to aid the police in fighting crime.
